Redpine's 802.11n 1x1 technology meets consumers' expectations for battery life and user experience for coverage and quality of voice calls over Wi-Fi networks.
The Lite-Fi RS9110 uses advanced power management techniques spread over system, algorithm and circuit levels.
"Unlike the conventional implementations which focus on silicon geometry to get lower power, we took system approaches to optimise the total average power", said Venkat Mattela, Redpine's Chief Executive Officer.
"Our research spanning over six years concludes that the silicon geometry has minimal effect on power consumption as compared to the effect on power due to wireless performance and system level optimisation techniques", said Mattela.
"Lite-Fi unveils intrinsic advantages of 802.11n for low power over 802.11b/g and we enhance it further with our and proprietary techniques to optimise the power for the total signal chain", he added.
"We expect the embedded Wi-Fi market to reach over one billion cumulative shipments by the end of 2010", said Philip Solis, Senior Analyst at ABI Research.
"As more consumer electronics manufacturers respond to the demand for high-speed wireless data capabilities, Wi-Fi chipmakers will be required to deliver solutions that address new size, cost and power paradigms".
The RS9110 is the first product from Redpine's Lite-Fi 802.11abgn product family.
The RS9110 was designed for ultra low power and extremely efficient wireless connectivity.
Using Redpine's proprietary processing core, the RS9110 maximises over-the-air throughput to deliver the most robust solution for multipath environments.
System-level power savings protocols and highly specialised signal processing algorithms all contribute to the RS9110's low power consumption.
Redpine's proprietary architecture is suitable for wireless convergence and the need for multiple standards on a single monolithic die.
The RS9110 is available in WLCSP and UFLGA packages.
Complete reference design kits are available in SD and SiP-based form factors.
A comprehensive software package that includes complete MAC firmware, reference drivers, manufacturing software and configuration GUI for Linux and Windows CE is available.
Support for host/client communications, information exchange between host and RS9110, WLAN configuration and power management is also available.
The RS9110 is a single-antenna, dual-band design that supports Bluetooth co-existence as well as the Wi-Fi Protected Setup program from the Wi-Fi Alliance.
Redpine's RS9110-based SD card reference design is Wi-Fi Certified for 802.11n draft 2.0 by the Wi-Fi Alliance and is the industry's first SDIO card to achieve this certification.
